Sep 14, 2023 · Hadean Eon, informal division of the Precambrian occurring between about 4.6 billion and about 4.0 billion years ago. It was the time of Earth’s initial formation—the accretion of dust and gases, collisions with larger bodies, the stabilization of its core and crust, and the rise of its atmosphere and oceans. Over time, Earth’s oxygen levels have changed significantly with varying levels of hydrogen, helium, carbon dioxide, nitrogen, and oxygen. 1. Hydrogen and helium were in the Hadean Eon. Earth’s early atmosphere was enriched with hydrogen and helium gases. But over time, Earth lost these gases because it wasn’t large enough to hold onto them.Geologic time scale with proportional representation of eons/eonothems and eras/erathems.
